The invention relates to the field of information security, in particular to an automatic screen unlocking method and device, electronic equipment and a readable storage medium. The method comprises the following Step S of sending a broadcast carrying a uuid value, when the terminal equipment determines that the equipment to which the broadcast belongs is connectable equipment according to the signal strength of the broadcast and the uuid value, receiving a Bluetooth connection establishment request sent by the terminal equipment, establishing a Bluetooth connection with the terminal equipment based on the Bluetooth connection establishment request, sending a notification message that the Bluetooth connection is successfully established to the terminal equipment, receiving an authentication login instruction sent by the terminal equipment based on the notification message, acquiring to-be-signed data carried in the authentication login instruction, signing the to-be-signed data according to the stored private key to obtain a signature result, and sending the signature result to the terminal equipment, so that the terminal equipment executes an automatic screen unlocking operation according to the signature result. According to the method and the device, the locked screen can be quickly and automatically unlocked through the automatic unlocking processing based on the Bluetooth connection, so that the method and the device have relatively high safety.
